Fix Ethernet Unidentified Network on Windows 11

Ethernet Unidentified Network on Windows 11 prevents your computer from accessing the internet through a wired connection. The system shows Connected but no internet or Unidentified network. This issue often relates to incorrect IP settings, driver errors, or router conflicts.

Follow these steps in order. Test your connection after each step.

Step 1 Check Ethernet Cable and Port

1. Ensure the Ethernet cable connects firmly to your PC and router.
2. Try a different Ethernet cable.
3. Switch to another LAN port on the router.
4. Check if the Ethernet port light blinks.

A damaged cable or inactive port often causes unidentified network errors.

Step 2 Restart Router and PC

1. Turn off your PC.
2. Unplug the router for 60 seconds.
3. Plug the router back in and wait for stable lights.
4. Turn on your PC.

This refreshes your IP address and clears temporary network conflicts.

Step 3 Disable and Re Enable Ethernet Adapter

1. Press Windows plus X.
2. Select Device Manager.
3. Expand Network adapters.
4. Right click your Ethernet adapter.
5. Select Disable.
6. Wait 10 seconds.
7. Select Enable.

This resets the adapter without reinstalling drivers.

Step 4 Update Ethernet Driver

Outdated drivers cause compatibility issues after Windows updates.

1. Open Device Manager.
2. Right click Ethernet adapter.
3. Select Update driver.
4. Click Search automatically for drivers.

You can also download the latest driver from your motherboard or laptop manufacturer website.

Step 5 Reset TCP IP and Network Settings

Incorrect IP configuration often leads to unidentified network errors.

1. Open Command Prompt as administrator.
2. Type netsh int ip reset and press Enter.
3. Type ipconfig /release and press Enter.
4. Type ipconfig /renew and press Enter.
5. Type ipconfig /flushdns and press Enter.
6. Restart your PC.

This resets your IP stack and clears DNS cache.

Step 6 Set IP Address to Automatic

If you previously set a manual IP, change it to automatic.

1. Open Control Panel.
2. Click Network and Internet.
3. Select Network and Sharing Center.
4. Click Change adapter settings.
5. Right click Ethernet.
6. Select Properties.
7. Click Internet Protocol Version 4.
8. Select Properties.
9. Choose Obtain an IP address automatically.
10. Choose Obtain DNS server address automatically.
11. Click OK.

This allows the router to assign a valid IP address.

Step 7 Disable Network Sharing Features

Some sharing settings create network conflicts.

1. Open Control Panel.
2. Select Network and Sharing Center.
3. Click Change advanced sharing settings.
4. Turn off Network discovery.
5. Turn off File and printer sharing.

Restart your computer and test the connection.

Step 8 Check Router DHCP Settings

Log into your router using its IP address, usually 192.168.1.1.

• Ensure DHCP is enabled.
• Restart the router from the admin panel.
• Update router firmware if available.

DHCP assigns IP addresses automatically. If disabled, your PC cannot receive a valid address.

Step 9 Disable Power Saving for Ethernet Adapter

1. Open Device Manager.
2. Right click Ethernet adapter.
3. Select Properties.
4. Go to Power Management tab.
5. Uncheck Allow the computer to turn off this device to save power.
6. Click OK.

This prevents random disconnections.
